IFRA usage calculator
Check how much fragrance oil or a single material you can use in a candle, soap, lotion or perfume, against the IFRA limit for that product.
Your supplier's IFRA certificate lists a maximum percentage for each product category. Ask for it if you do not have it.
Find the material's limit in the current IFRA Standards or its supplier's documentation. Most Atlas Origins materials are 10% dilutions.

How the calculator works
The International Fragrance Association (IFRA) sets standards that limit how much of certain materials can be used in a product. The limit depends on the product: a lip balm gets far stricter limits than a candle, because of how much contact it has with skin.
Fragrance oil mode
Use this when you buy a ready-made fragrance oil. Its IFRA certificate gives a maximum percentage for each product category. Enter the figure for your category and the load you plan to use, and the calculator tells you whether you are within the limit and how many grams that is for your batch.
Single material mode
Use this when you build your own fragrance. A material's level in the finished product is its percentage in your concentrate, multiplied by the percentage of concentrate in the product, divided by 100.
Example: a material makes up 5% of your concentrate, and the concentrate is 20% of your eau de parfum. In the finished perfume the material is at 5 × 20 ÷ 100 = 1%. If that material was a 10% dilution, it is actually at 0.1%.
Questions
What are IFRA categories?
IFRA groups products into categories by how they are used and how much contact they have with skin. Lip products are Category 1, fine fragrance is Category 4, rinse-off soap is Category 9 and candles are Category 12. The less a product touches skin, the looser the limits.
Where do I find the IFRA limit?
For a ready-made fragrance oil, ask your supplier for its IFRA certificate, which lists the maximum percentage for every category. For a single material, check the current IFRA Standards published by the International Fragrance Association, or the material supplier's documentation.
Is IFRA compliance a legal requirement in Malaysia?
IFRA Standards are an industry code rather than a law. Retailers, marketplaces and contract manufacturers widely expect them, though, and cosmetic products sold in Malaysia must be safe under the ASEAN Cosmetic Directive, which the National Pharmaceutical Regulatory Agency (NPRA) administers.
Do candles and diffusers need IFRA compliance?
Yes. Category 12 covers products not meant for skin contact, such as candles and reed diffusers. Its limits are looser, but some materials are still restricted or prohibited.
How do dilutions change the result?
If a material is sold as a 10% dilution, only a tenth of what you weigh is the material itself. Tick the dilution box in single material mode and the calculator accounts for it.
This calculator gives guidance only. Always confirm against the IFRA certificate, the safety data sheet and the current IFRA Standards before you make or sell a product. See our terms.
